  2. 1. Oscillatory Ca2+ signaling in glucose-stimulated murine pancreatic β-cells : Modulation by amino acids, glucagon, caffeine and ryanodine

    Author : Meftun Ahmed; Per Lindström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; pancreatic β-cells; islets of Langerhans; glucose; Ca2 oscillations; Ca2 transients; potassium; ryanodine; caffeine; glucagon; cAMP; inositol 1; 4; 5-trisphosphate; fura-2; glycine; alanine; arginine; Ca2 channels; rats; lean mice; ob ob mice; leptin; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : Oscillations in cytoplasmic Ca2+ concentration ([Ca2+]i) is the key signal in glucose-stimulated β-cells governing pulsatile insulin release. The glucose response of mouse β-cells is often manifested as slow oscillations and rapid transients of [Ca2+] i. READ MORE

  4. 2. Neogenesis and alloxan toxicity in pancreatic islets, with special reference to the transplanted human β-cell

    Author : Björn Tyrberg; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cell biology; Alloxan; β-cell; diabetes; differentiation; growth; insulin secretion; nephrectomy; ob ob; pancreatic islet; transplantation; guinea-pig human; mouse; Cellbiologi; Cell biology; Cellbiologi; medicinsk cellbiologi; Medical Cell Biology;

    Abstract : The aim of this work was to study whether adult human pancreatic β-cells have the capacity to proliferate in culture and after transplantation to the renal subcapsular space of mice. An immunosuppressive regimen for human islet discordant xenotransplantation to mice was designed. READ MORE

  5. 3. Effects of growth hormone on bone tissue in transgenic mice

    Author : Jonas Sandstedt; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Growth hormone; bone; ovariectomy; orchidectomy; growth; Interleukin-6; titanium; transgenic mice;

    Abstract : Growth hormone (GH) affect bone-tissue in both humans and rodents. Also sex steroids are important for growth and the maintenance of normal bone physiology. The specific aims of this study were to investigate how high levels of GH affects bone tissue in mice and to determine whether these effects are dependent on an intact gonadal function. READ MORE

  6. 4. Localization of lipoprotein lipase in mouse pancreas, kidney and placenta : impact of metabolic disturbances on cellular distribution and activity regulation

    Author : Rakel Nyrén; Gunilla Olivecrona; Paolo Parini; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lipoprotein lipase; pancreas; kidney; placenta; angiopoietin-like protein 4; high-fat diet; obesity; mice; PET CT; nutritional status; triglyceride; GPIHBP1; medicinsk och fysiologisk kemi; Medical and Physiological Chemistry;

    Abstract : Lipoprotein lipase (LPL) is the key enzyme for metabolism of triglycerides in plasma lipoproteins. In recent years many new facts about the enzyme and its regulation have been uncovered. The endothelial membrane protein GPIHBP1 translocates LPL through endothelial cells and holds the enzyme in place at the luminal side of the capillary endothelium. READ MORE

  7. 5. Methylsulphonyl-chlorobenzenes and the olfactory system : Comparative toxicity of the 2,5- and 2,6-dichlorinated isomers in mice

    Author : Fariba Bahrami; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Developmental biology; Utvecklingsbiologi; Developmental biology; Utvecklingsbiologi; toxikologi; Toxicology;

    Abstract : Methyl sulphone metabolites of chlorinated aryl hydrocarbons are persistentenvironmental pollutants that can bioaccumulate in animals and humans. Little is known about the toxicological effects of these metabolites and this thesis is an attempt to increase this limited knowledge. READ MORE
